- The aim of this study was to compare the effect of different nutritional screening tools on predicting the risk for mortality in patients on maintenance hemodialysis (MHD).A cohort of 1025 patients on MHD were enrolled from eight hospitals. The malnutrition-inflammation score (MIS), objective score of nutrition on dialysis (OSND), and geriatric nutritional risk index (GNRI) were measured at baseline. All-cause mortality and cardiovascular (CV) mortality were the major study outcomes.The median follow-up duration was 28.1 mo. The MIS (per SD increase, hazard ratio [HR], 1.35; 95% confidence interval [CI], 1.18–1.55), the OSND (per SD decrease, HR, 1.24; 95% CI, 1.09–1.42), and the GNRI (per SD decrease, HR, 1.26; 95% CI, 1.10–1.43) were significantly associated with the risk for all-cause mortality. More importantly, the mortality predictability of the MIS appears similar to the GNRI (P = 0.182) and greater than the OSND (MIS versus OSND: P = 0.001; GNRI versus OSND: P = 0.045). Similar results were found for CV mortality.Each of the three nutritional screening tools was significantly associated with an increased risk for all-cause and CV mortality. The mortality predictability of the MIS was similar to the GNRI and greater than the OSND.
